The Eibach PRO-KIT is the perfect answer for most frequently-driven street cars. It's our legendary sport spring system that dramatically improves both a vehicle's performance and appearance.

PRO-KIT precisely lowers your car's center of gravity, reducing squat during acceleration, body roll in corners and excessive nose-dive under braking. When combined with Plus-1 or Plus-2 wheels and tires, the Eibach PRO-KIT is the finishing touch to a winning recipe for performance. PRO-KIT also reduces excessive fender-well clearance, making your car look just as hot as it performs.

Every Eibach PRO-KIT is designed and tested by our suspension engineers and performance driving professionals to deliver aggressive good looks and high performance handling, without ever compromising safety or ride quality. By using our proprietary, progressive spring design, PRO-KIT Performance Springs provide the ultimate balance to take your passion for driving to a whole new level.

* Your results may vary. As we have learned from racing and independent testing has proved - lowering your car or truck's ride height also improves your aerodynamic efficiency by forcing more air over the car and less underneath (where most of the drag is found on any vehicle), resulting in higher top speeds on the track and better MPG on the highway.
